To multiply in Excel by a constant, simply select the cells you would like to multiply, click the multiplication sign, and then type in the constant you would like to multiply the cells by. The result of the multiplication will be displayed in the selected cells.
You can use the following basic formula to multiply a column by a constant in Excel:
=CELL*CONSTANT
For example, you can use the following formula to multiply the value in cell A1 by 5:
=A1*5
You can then click and drag this formula down column A to multiply every value in column A by 5.
The following example shows how to use this formula in practice.
Example: Multiply Column by a Constant in Excel
Suppose we have the following list of values in Excel:
We can use the following formula to multiply the value in cell A2 by 5:
=A2*5
Next, we can hover over the bottom right-hand corner of cell B2 until a tiny “+” appears. Then click and drag down to all of the remaining cells in column B:
All of the values in column B are equal to 5 times the values in column A.
For example:
- 10 * 5 = 50.
- 15 * 5 = 75.
- 18 * 5 = 90.
- 20 * 5 = 100.
- 25 * 5 = 125.
To multiply by a different constant, simply change the value used in cell B2.
For example, to multiply by 9 simply use the following formula:
=A2*9
Then click and drag this formula down to all of the remaining cells in column B.
Each value in column B will now be equal to 9 times the values in column A:
For example:
- 10 * 9 = 90.
- 15 * 9 = 135.
- 18 * 9 = 162.
- 20 * 9 = 180.
- 25 * 9 = 225.
And so on.
